The annual Antarctic ozone hole reached an average area of 8.9 million square miles (23.2 million square kilometers) between Sept. 7 and Oct. 13, 2022. This depleted area of the ozone layer over the South Pole was slightly smaller than last year and generally continued the overall shrinking trend of...
River longer than the Thames beneath Antarctic ice sheet could affect ice loss
An unexpected river under the Antarctic ice sheet affects the flow and melting of ice, potentially accelerating ice loss as the climate warms.
Revolutionary technique to generate hydrogen more efficiently from water
Researchers have made a serendipitous scientific discovery that could potentially revolutionize the way water is broken down to release hydrogen gas -- an element crucial to many industrial processes. The team found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis, where water...
High-res maps of entire polar regions provide new clues for climate researchers
A team of researchers has released four more years of high-resolution imagery data, which has been added to eight years of previous data, to create the most detailed polar region terrain maps ever created.
‘Forever chemicals’ persist through wastewater treatment, may enter crops
PFAS (per-and polyfluoroalkyl substances) persist through wastewater treatment at levels that may impact the long-term feasibility of 'beneficial reuse of treated wastewater,' according to a new study.
Fighting tumors with magnetic bacteria
Researchers are planning to use magnetic bacteria to fight cancerous tumors. They have now found a way for these microorganisms to effectively cross blood vessel walls and subsequently colonize a tumor.
Neuroimaging study reveals functional and structural brain abnormalities in people with post-treatment Lyme disease
In a study using specialized imaging techniques, researchers report distinctive changes in the 'white matter' and other brain tissue physiology of those with post-treatment Lyme disease, a condition affecting 10% to 20% of the nearly half a million Americans who contract Lyme disease annually.
Sensor disguised as a sea turtle egg allows conservationists to remotely predict nest hatching time
A new low-cost sensor designed to resemble a sea turtle egg enables scientists to monitor nests remotely and predict when hatchlings will emerge almost to the day -- providing valuable information for conservation efforts and turtle nest management.
Metabolite product from pomegranate: Researchers identify way to boost tumor-fighting immune cells
Researchers have succeeded in identifying a new approach for the therapy of colorectal cancer. In preclinical models and studies on human immune cells, they found that urolithin A, a metabolite product from pomegranate, sustainably improves the function of immune cells in their fight against cancer. After treatment with urolithin A,...
Synthetic genetic circuits reprogram plant roots
Controlling gene activity is important for engineering plants for improved bioenergy crops and other applications. This research developed synthetic genes that use Boolean logic gates to achieve specific patterns of gene expression within a plant. The researchers used these gene circuits to redesign the root architecture by tuning the number...
